堵塞工况下过滤器强度研究

Study on Strength of Filter under Blockage Condition

摘要: 为了摸清管道过滤器在非正常工况下的承压极限，本文通过试验研究了滤网堵塞工况下过滤器的结构强度，同时借助仿真软件分析了过滤器在堵塞工况下的静强度及骨架失稳。结果表明：在滤网全堵塞工况下，过滤器极可能出现因骨架屈曲失稳而失效。

Abstract: The structure strength of filter under the condition of blockage is studied by experiment to find out the pressure limit of pipeline filter under abnormal working condition. Meanwhile, the static strength and buckling instability of the filter are analyzed by the finite element analysis method. The results show that the filter is likely to breakdown due to the buckling instability of the filter under the condition of complete blockage.
